Kentucky State Income Tax Guide (2026)
Kentucky applies a flat 3.5% income tax on all taxable income after a modest standard deduction.
1. Kentucky Flat Tax Rate
Kentucky applies a single flat income tax rate of 3.5% to taxable income. Unlike progressive states, the same rate applies whether you are an entry-level worker or a high earner, which makes the calculation straightforward.
2. Deductions and Conformance
For 2026, the Kentucky standard deduction is $3,260 for single filers and $6,520 for married couples filing jointly. Pre-tax 401(k) contributions, HSA contributions, and employer health premiums reduce your Kentucky taxable income.
